Sahih Muslim Book 1, Hadith Number 296.

Chapter : Description of the period in which Iman would not be acceptable to Allah.

It is narrated on the authority of Abu Huraira that the Messenger of Allah (may peace be upon him) observed: When three things appear faith will not benefit one who has not previously believed or has derived no good from his faith: the rising of the sun in its place of setting, the Dajjal, and the beast of the earth.
